摘要
利用微生物发酵技术,通过正交试验研究了温度、pH值、发酵时间、接种量等因素对热带假丝酵母菌处理马铃薯淀粉废水的影响。结果表明,在温度为28℃、pH值为5.5、发酵时间为28 h、接种量为10%的条件下,废水处理效果和热带假丝酵母菌生长情况最佳,且经处理后废水CODCr、SS、色度去除率分别可达到76.0%、73.5%、77.1%,同时可获得9.53 g/L的单细胞蛋白。
With the help of microbial fermentation, the influences of temperature, pH value, fermentation time, and inoculation amount on potato starch wastewater treatment by candicla tropicalis were studied through orthogonal test. The results showed that, under the condition that, the temperature was 28 ℃, the pH value was 5.5, the fermentation time was 28 h, the inoculation amount was 10%, the best treatment effect of the wastewater and the optimal growth condition of candida tropicalis were obtained at the same time. Besides, the removal rates of CODcr, SS and chroma reached 76.0%, 73.5% and 77.1% respectively with 9.53 g/L of single-cell protein produced as well.
